The answers do not match the question, the question says:
You need to onboard the devices to Microsoft Defender for Endpoint.
First you need to turn Onboarding under settings under Microsoft Defender for Endpoint, plus download the package scripts to run on devices, or under Advanced Features, turn on the Intune Connector AND turn on the Defender for Endpoint Connection in Endpoint Manager (2x ways). From the question the computers are not onboarded yet. Then you configure the various ASR, EDR etc.... I guess if I get this on the exam 1:1 I will answer as per the answers here
